Hi,
There are significant changes between corosync 2.x and 3.x and similarly
between pacemaker 1.x and 2.x. To cover those and support the new
versions, we created pcs-0.10 branch. The old versions are supported by
pcs-0.9 branch.
RHEL 7 ships corosync 2.x and pacemaker 1.x, so we build pcs-0.9.x for
it. Corosync 3.x and pacemaker 2.x are shipped in RHEL 8, so that's
where pcs-0.10 goes.
RHEL 8 also ships new version of ruby and python. So on top of
modifications needed for corosync 3.x and pacemaker 2.x support, we used
the opportunity to get rid of legacy code supporting those end-of-life
python and ruby versions.
Regards,
Tomas

Hi folks,
Thank you for your time and will to help.
We are in the middle of a high pressure because some problems with
RHEL HA Cluster/Corosync+Pacemaker/DRBD and we arrived at the point
that we upgraded corosync 2.4.3 to 3.1 and pacemaker 1.1.20 to 2.1 but
then our setup gives errors with the command
“pcs property set no-quorum-policy=stop”.
The error is:
/No such file or directory', 'command':
'/usr/libexec/pacemaker/pengine metadata’/
Indeed //usr/libexec/pacemaker/pengine /does not exists, I assume it
is OK, because in the new pacemaker 3.1 the internal structure was
changed..
In the midtime we found out that we could archive the same setting
using crm_attribute --name no-quorum-policy –update stop.
My questions are:
* Is there a reason that pcs has no build for RHEL 7?
I can only answer this question, newer version of pcs needs ruby and
python in versions that are not supported on RHEL7 and even if we can
build the package, it won´t run.

* Is the crm_attribute the right choice for
setting cluster properties
and will cover all usecases?

Thank You!
